Definitions

  • compositions and methods relating to polymer conjugates and, in particular, to polymer conjugates having pendant side groups comprising ring moieties.
  • Polyphenols are natural products comprising more than one phenol moiety per molecule. They are commonly produced by plants as secondary metabolites for purposes such as defense against predators, structural integrity, and protection from harmful solar radiation. Some polyphenols are useful, for example, for their medicinal antioxidant properties and their ability to affect specific biological processes. Polyphenols are also known to hydrogen bond with polymers such as PEG and PVP and are attractive as complexing agents because phenol groups typically form stronger hydrogen bonds than, for example, carboxyls, despite being weaker acids. Their relatively weak acidity makes them attractive for biomedical applications since their hydrogen bonding capabilities are generally preserved under physiological pH. SUMMARY OF THE INVENTION
